A great idea for a bike – take a look and decide if this is a worth project on kickstarter.
How to seperate an egg yolk
The days before photoshop.
I remember well the one with the pickle.
I remember Heathkits from my youth. Back then, electronics were not disposable items and you could build your own appliance or gadget after countless hours of painstaking work for only about twice what a new one would cost. They were very high quality, though, in a day when quality still existed and mattered.
The detailed instructions, the carefully labeled parts (especially the myriad resistors) and, especially, the smell of rosin-core solder heated and the sight of the wisp of burnt flux smoke rising from the pool of liquid lead.
A friend of mine across the street even made an entire color television. It burnt out one day while we were watching football (there was always the danger you would make a mistake – I view that as a feature, not a bug).
I still use a Heathkit audio amp I built in 1982. It sounds better than anything made today.
